3:06 You can check the [x] Expose Position and [x] Expose Rotation on the right side of the screen. This allows you to access these via an IK Rig node inside of a animation blueprint at runtime. Works better than the FABRIK node IMO.

not working in ue5.4. I move the ik solver (the cube) and arm stays there and only the cube moves

double check your work, should still work in the latest version of unreal. although, since this is mostly used for retargeting, you might not need to use this anymore with unreal 5.4 anyway since it's auto retargeting has gotten a lot better.

@@thegamedevcave i figured out. Turns out, for some reason I had two wrist joints because I created the rig from autorig pro in blender. So I was selecting the wrong wrist joint, yet both wrist joints had the same name.

So if you create a recoil animation for a pistol and put that pistol in a socket in Manny's hand, his body will react to the recoil animation?

How can I integrate this with ctrl rig? I have a ctrl rig set up but the rig moves all bones, which isn’t what I want, whereas IK ctrl has the set up structure I need but I have to animate the rig

this IK rigging is mostly what is used to retarget (or at least, it was before auto retargeting become a lot more powerful in recent updates) this is separate from control rigs. here's a video about control rigs ": kzfaq.info/get/bejne/rtiKoLB6ls3Pj3k.html and a video about the new modular control rigs in unreal 5.4 : kzfaq.info/get/bejne/gNl3ZcWjrNLJpqM.html

I don't think the unreal dev community respects my time. I see there are solutions on videos already but no packages I can import? I mean great, the creators want to get some money by advertising their patreons. But come on, just show the video, have the package, and advertise your patreon. I'm not trying to reinvent the wheel.

I only link to my patreon with project files when a video contains something that was actually created, in videos like this i am just showing off a feature so there isnt any project files to share.. i am not going to make people pay for what is essentially an empty project

Dude im with you up till the point where you say "see you can move the arm" and I CANT the control just moves around no arm movement

What can I use IK Rig for?

@thegamedevcave 4 ай бұрын

These rigs are mostly used if you want to take animations from 1 skeleton and apply them to another skeleton.

Thank you so much! But do you know how can i make that a IK in attache to a 3d Objekt ( for example a cube ) so that if a move the 3d Objekt i also move the IK. 🧐

Please please help me. I want to use Unreal 5 to animate with and render because its amazing. BUT my rig was in FK so I followed this tutorial to make it an IK, and I came to a huge problem. How do I actually use the IK rig? I see no option in the "IK rig blueprint" to animate or keyframe, so I assume to animate with it you would need to go to the Level Sequncer, but I can't figure out how to get the IK rig into the Level Sequencer. Can you please help me?

@thegamedevcave 5 ай бұрын

you're looking at the wrong thing for that, you need to setup a control rig for that, this IK rig is for retargeting and i believe it also helps with real time IK. for anothion you need to set up a different kind of rig, which I also have a video on kzfaq.info/get/bejne/rtiKoLB6ls3Pj3k.html

Weird, it won't let me select a skeleton when I ad an IK rig. My version must be different?

@hiQer 6 ай бұрын

Same here and I fidn this issue on the forum on reddit etc. But no one knows why this happens. It seems that when you add a preview it work good enough. But it does not ASSIGN the skeleton to the rig..So this is an issue I believe.. The problem is there sinds many months.

This looks easy, but I still don't understand the relation between this IK Rig and Control Rig. Control rig looks very similar too me, you have a visual marker and then you need to create own logic to change the pose based od visual markers. IK rigs presented in the video looks like simplified version, you jus set some predefined solver, but how thy now how exactly is possible to move for real human to look it natural? When I should use IK rig and where Control rig?

@thegamedevcave 7 ай бұрын

they do overlap a lot, personally I am also more familiar with control Rig. Setting up a full IK rig is also needed for retargeting animations between different skeletons though, and from what I gather, it's more meant for real time IK on runtime (although control rig can also do that with animationBPs I believe) In general, this is a nice quick option but in most cases you are probably best off setting up a control rig instead.

For example for pusgh button animaitons, where character need to move hand to exact position, IK rig is always used.

But how to implement this in sequencer animation. there is no tutorials

@thegamedevcave 11 ай бұрын

for that you'll want to use control Rig, it's a bit more involved of a process to set up but it allows you to animate your skeletal meshes quite nicely. I've got a tutorial on that coming up pretty soon but you should also be able to find some go do stuff out there on KZfaq already!
